%N Decimal expansion of Cp(4), the molar specific heat of an tetraatomic ideal gas at constant pressure, in J mol^-1 K^-1.
%C J mol^-1 K^-1.
%C Also the decimal expansion of Cv(5), the molar specific heat of a pentaatomic gas at constant volume.
%C The molar specific heat of an n-atomic gas at constant pressure and volume can be calculated respectively with the following formulae:
%C - Cv(n) = (n + 1/2) R;
%C - Cp(n) = (n + 3/2) R;
%C Where R = Cp(n) - Cv(n) = Cp(n) - Cp(n-1) = A081822 is IUPAC's value of the gas constant.

%F Cp(4) = (4 + 3/2) * R = 11/2 * A081822.
%F Cp(4) = Cp(3) + R = Cv(4) + R = A272004 + A081822.
%e Cp(4) = Cv(5) = 45.7295289 J mol^-1 K^-1.
